Since the beginning, automotive engines have been cooled by air-liquid systems. While this remains state-of-the-art, new applications, such as air-liquid charge air coolers and contact battery coolers, are increasing the thermal burden on the main system with their indirect loops.

Together with customers, we have designed, and are still developing, new tubes with the characteristics that enable them to meet the new challenges of today's cooling devices – devices that are not located near the cooling air flow at the front of the vehicle.

In addition to the traditional flat-oval tubes, which are offered in dozens of dimensions, we manufacture welded B-type tubes and dimpled surfaces.
